Rb26 - Oil Issues

[R32 Stuart]

Here's two options that both work!

R32 is a bit ugly but works, drain from valve cover catch can back to rear turbo drain is general knowledge our biggest improvement is venting valve cover ie from oil cap back to catch can.

Under blowby conditions, this stops oil pumping from valve covers or can, as it is vented both ends - no longer wants to push the oil out, lets engine breathe.

Prior to this the R32 - standard engine and sump - would fill 3 ltr catch can in 40 second hillclimb - engine still strong, no fumes, remembering if there is 3 lts of oil in catch can 2ltrs in valve cover doesn't leave much for the engine! Thats why oil pumps blow up etc etc For FoSC regularity events as a safety measure ran a holley blue fuel pump from 3ltr catch can back to dip stick tube, this also worked great under extreme conditions

R33 - most of this setup was existing on car, eg 9ltr high octane sump, twin catch cans main drain back to sump - we added the filler cap back to rear valve cover can hose and earles one-way valve catch can back to sump - this also stopped it filling the catch can in 5 laps at Wakefield - following approximately 75 laps at Oran Park GP - breather hose from main catch can, probably half a dozen drops of oil!
